To aZZ whom it may conce/rn:

Be it known that I, Gunn J. Combien, e citizen of the United States, one. a resiiieni of the city of New York, county and Siete oiiiew York, have invented ce1-tain new sind useful improvements in Seivinniiinshines, of which the following is a. specifica tion.

My invention relates to im rovemenie in devices for securing together s ets of peper oi' ille like, for the purpose of binding the same at or neel'4 the margin thereof.

One object of my invention is to proviiie' a simple and efficient device for passing ihre-aci or cord through the sliees of peper or the iiiie, and forming a ioop on one side thereof, and *alien Carrying the thread ende through the ioop in order "10 peoperijv bind 1ihe eiieeis together. a

A. *furiier object of my invenion is it@Y so arrange the lvarious parte oi the device ihat the thread may be ont oii at the proper point in oi'fiei to leave sniicient 'threed ends, and 'to so poeiiion ond arrange the other paris oi the device iiae it is simple and efficient in operation and easy and eiieeip` oi construe tion.

In this position all of the parts renini'n the same except that 'the needle has been partially with dreven, but the lingers 54 and 55 have engaged and held aloop of thread 15, on thev oppositey side of the material from which the needle entered. Upon allowing the handles l and 2 to still further separate 'Slightly a pin 64, on the eem member 31,

engges the depending arm of the latch 29, thereby withdrawing the latch from en-' gsgement 'with the projection 27, so that the sliding bar 2l isreleased, and is quickly pulled forwagd -underthe action of the spring 25, thus Acausingthe knife26to cooperate with the knife edge 27', to severthe thread. The bar 2l also carries a. projecting arm 66, which has at its outer end a transverse pin G7, adapted' to engage vthe thread l5, before the knife 26 seversthe thread, so as to pull a sufficient amount of the threadthrough the needle-in order that' when it is severed a sniiicient length of thread. will be-'let't above the material, so that. the thread ends` will be long enough. lt will also'be noted that the length of the thread hanging from the needle 7, after it is se. ered. le.' glh of thread vprojecting above from the nmlerinl ll, Upon now allowing handles l and 2 to separate still farther the parts assume the ln vthis position the cam face 82 has again engaged the roller 33, on the lever 34, and the cam face at 3l) has again allowed the pin at 38, 'on the so that the bar 3T assumes its' original position, as in Fig. l.A The thread ends et 68 are, however, still held Within the eye 4l,

two small projections 69 (see Fig. Il), between which projections the'thrend' ends 68,

are engaged, as shown 'in FigQtf-so that i upon the arm 37 essuming'thegpisition in G', the thread-ends' @$8 are -forced between the ngers 54 and, as' shown in Fi l 6. Upon now allowing :in 2 to separate until-.theygreach their ini,- tial position, the parts assume' the position shown in- Figl 7. This movement causes the shaft 3 to rotation, so chata pin .71securedto the cam engages the arm 62 of the latch 60, so as to disengage the latch G0 from the projectionv 59, and allow the bar 50 to he' rapidly'withdrawn, springy 56.*' This causes the lingers 54 end toberpidly drawnthrough the is substantially the same .as the the- Aposition shown in 6.
